“Most people think King would be the last person to own a gun. Yet in the mid-1950s, as the civil rights movement heated up, King kept firearms for self-protection. In fact, he even applied for a permit to carry a concealed weapon. A recipient of constant death threats, King had armed supporters take turns guarding his home and family. He had good reason to fear that the Klan in Alabama was targeting him for assassination.”
